2012 Mercedes-Benz GLK-Class Review

SUV styling with car driving dynamics

Reviewed by Automotive on

The GLK may be Mercedes' smallest SUV, but it has the most flair to it. At first glance, the GLK may resemble its larger GL sibling, but as you look longer at the GLK, you quickly notice its intricate lines, adding sportiness to this compact SUV that no other Mercedes sport/utility can offer. This vehicle does have flaws though, including its lack of off-road capability, and only one engine is offered.

The only engine available for the GLK350 is a 3.5-liter V-6. This engine produces 268 horsepower and 258 lb-ft of torque, and is paired with a seven-speed automatic transmission with available all-wheel drive. Acceleration isn't bad, as it hits the 60 mph mark in 6.5 seconds.

Mercedes features top-of-the-line technology in each of its vehicles, and the GLK is no exception. A 100-watt Audio 20 system is standard, which features a CD slot, telephone keypad, MP3 plug-in and Bluetooth interface. Optional on the SUV is a COMAND navigation system complete with a seven-inch color display screen and a hard drive with map data for all of North America.

The Range

Body Style: Crossover SUV
Engine: 3.5-liter V-6
Transmission: seven-speed automatic
Models: GLK350, GLK350 4Matic

What's New

Entering the 2012 model year, the GLK only receives one minor change. The optional media interface cable, used for connecting an iPod, has been relocated to the center console. In 2011, the GLK received numerous changes including a premium leather steering wheel, and an AMG sport package that features AMG bumpers, 20-inch wheels, LED daytime running lights, and aluminum roof rails.


To some, the GLK may look like a scaled down G-Class, but in reality, the GLK features a much sportier exterior than its larger relative. This compact SUV features intricate lines that surround the vehicle, as well as an integrated rear spoiler. Also noticeable is its projection headlights and steep windshield.


The interior of the GLK is very clean and luxurious, although the steering wheel is a little cluttered. The leather-wrapped steering wheel contains 12 buttons, controlling phone and audio information among others. There is certainly no lack of technology in this vehicle. It features a 100-watt Audio 20 system, along with a COMAND Navigation system. The navigation system features a seven-inch screen that has map data for all of North America.

Performance & Handling

The GLK is available with only one engine. It is powered by a 3.5-liter V-6 that produces 268 horsepower and 258 lb-ft of torque. This is paired with a seven-speed automatic transmission. This engine accelerates the GLK from 0-60 mph in just 6.5 seconds. It is fitted with a Standard Agility Control suspension system that provides both soft and stiff shock absorbers that allow for a comfortable, versatile driving experience.


The GLK is equipped with numerous safety features, including a plethora of airbags; two-stage adaptive airbags for the driver and front passenger, driver's knee airbag, front seat-mounted side and pelvic airbags, and curtain side airbags. Also, active front head restraints, known as Neck-PRO, move forward and upward to support the head in the event of a collision.
